UNITED STATES WILLIAM D. KYLE, OF MILWAUKEE, WISCONSIN.

STRAIN INSULA'IOR.

Application filed December 30, 1921.

To all whom it may concern:

Be it known that I, VILLIAM D. KYLE, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofIVisconsin, have invented new and useful Improvements in Strain Insulators, of which the following is a description, reference being hadto the accompanying drawings, which are a part of this specification.

The invention relates to strain insulators.

The object of the invention is to improve upon the usual stiff metalclevis and its connection w'th the bolt running through the insulator,by providing a flexible cable forn1- ing the clevis and firmly anchoringthis cable in a simple and effective manner for its connection with thebolt. By this arrangement a standard size clevis may be used for allsizes of strain insulators, whereas it has been necessary, with thestiff metal clevis, to keep different sizes on hand to fit differentsizes of insulators.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. l is a front eleva tion view .of a deviceembodying the invention, parts being shown in section; I 2 is a sideelevation view thereof; Figs. 3-? and l: are vertical sectional viewsshowin slightly modified constructions.

In the drawings the numeral 4 designates a strain insulator usually madeof porcelain and having a hole 5 therein for the guy cable and a groove6 extending around one end to opposite ends of said hole and an opening7 extending at right angles to said hole 5 receiving the clevis bolt 8.

.=.ccording to the present invention the clevis is formed by a flexiblemetal cable 9 and means for operatively connecting the ends thereof tothe bolt 8.

For connecting the ends of the cable 9 with the bolt 8. I preferablyprovide eyes 10 to which the ends of the cable are secured in eachinstance by casting the metal forming the eye about the coiled end 11 ofthe cable. The metal forming the eye is preferably cast iron or lead.here lead is used hubs 12 may be formed integral with the main portionof the eye and project into the flared ends 13 of the opening 7, asshown in Fig. 3, or the hubs 12 extend into meeting engagement, as shownin Fig. 4. These Serial No. 525,843.

eyes are made long enough to form a good bearing connector with thebolt.

IVith this construction the ends of the cable are securely embedded inthe eyes and these eyes are mounted on the bolt on either side of theinsulator eland drawn into engagement therewith by tightening up the nut14: of the bolt 8. The cable clevis readily adapts itself to straininsulators of different sizes and by making this cable loop of a size totake the largest size insulator it may be used on all other sizes sothat neither the manufacturer nor the user has to keep a stock ofclevises of different sizes on hand, as the one standard clevis issuitable for all sizes of insulators.

I desire it to be understood that this invention is not to be limited toany specific form or arrangen'ient of parts except in so far as suchlimitations are specified in the claims.

IVhat I claim as my invention is:

1. In a strain insulator, the combination with the insulator, and thebolt passing therethrough, of a loop of flexible cable adapted to takeinsulators of different sizes, and means for securing the ends of thecable to the bolt on opposite sides of said insulator.

2. In a strain insulator, the combination with the insulator, and thebolt passing therethrough, of metal eyes fitting onto the bolt onopposite sides of the insulator, and a loop of flexible cable having itsends secured to said eyes.

3. In a strain insulator, the combination with the insulator. and a boltpassing there through, of metal eyes fitting onto the bolt on oppositesides of the insulator, and a cable loop having its ends embedded insaid eyes.

t. In a strain insulator, the combination with the insulator, and a boltpassing therethrough, of metal eyes fitting onto the bolt on oppositesides of the insulator, and a cable loop having coiled ends embedded insaid eyes.

5. In astrain insulator, the combination with the insulator having aclevis bolt opcning with flared ends, and a bolt passing through saidopening, of metal eyes fitting onto the bolt and having extensionsseated in said flared ends, and a cable loop having its ends secured tosaid eyes.

In testimony whereof I afiix my signature.

IVILLIAM D. KYLE.
